Question

我在一个函数中有4个查询，这是nsert创建一个简历。这包括教育，就业，技能和加入他们的主要简历。

现在，当他们创建简历时，他们不会总是填写所有不同的表格来创建上述内容（教育，工作，技能），但我需要返回1条成功消息。我不能在rowcount上使用if else：因为这会返回所有这些或没有的值，所以我怎么能回应：

Alert::success('adding_resume', true);

即使某些表格中的表格空了，也会一次;

public static function create_resume()
{

    // Let's define the rules and filters
    $rules = array(
        'resume_title'    => 'max_len,100|required',
        'expected_level'    => 'max_len,100|required',
        'expected_salary'    => 'required|max_len,12|integer',
        'work_location'    => 'max_len,100',
        'year_experience'    => 'max_len,100|integer'
    );


    //validate the info
    $validated = FormValidation::is_valid($_POST, $rules);

    // Check if validation was successful
    if($validated !== TRUE):    

        //exit with an error
        exit(Alert::error(false, true, $validated));

    endif;

    //initate db
    $database = DatabaseFactory::getFactory()->getConnection();


    //sql to run
    $sql = "INSERT INTO resumes

这对你来说似乎是一种奇怪的方式，只是尝试插入所有内容而不检查任何内容，但你可以这样做：

创建一个最初设置为false的布尔值。
在每次查询后，检查结果。
如果结果为true，则将布尔变量更改为true。如果结果为false，请不要更改布尔变量。
运行所有查询后，如果您的布尔变量为true，则至少有一个查询成功。

示例代码：

$good_query = false;

<build sql query for resume stuff>

$check = $resume->execute(<blah>);

if ($check) { $good_query = true; }

<build sql query for employment stuff>

$check = $resume->execute(<blah>);

if ($check) { $good_query = true; }

<build sql query for education stuff>

$check = $resume->execute(<blah>);

if ($check) { $good_query = true; }

<build sql query for skills stuff>

$check = $resume->execute(<blah>);

if ($check) { $good_query = true; }

如果$ good_query在结尾处为真，则至少有一个查询成功。

如果不是全部运行，则从多个查询返回成功消息
